Hi Michael,
This post really caught my eye! I guess I around 1,100 CDs, and of all of them, there were only 4 that I have found unlistenable. they would be"
Joe Jackson- Look Sharp
Derek and the Dominoes - the double album on one disc
Gin Blossoms- first album
Yes- Close to the Edge
The Yes disc was the one that bothered me the most, because I love the music. I had it for many years, and every time I tried to listen to it, I ended up taking it off within a couple of minutes because it sounded so bad. This January, I bought a remastered copy, and it sounds (as you said) great. So happy that it was remastered! It made a huge difference.
